This system was originally set up by Andy Schofield and you can find his email address on his homepage
In 2009, when the website came online, Andy had time to manage this. Now it carries on running on an ad-hoc basis so he is unable to respond to requests for any changes to the way the system works – or to deal with bug reports. That it works at all is a miracle! If someone would like to maintain and run the system, then please let Andy know.
